Figure 5. Impact of changes of fixed parameter values on the estimates of α, β_inside and β_outside.

(a): relative error for α; (b): relative error for β_inside; (c): relative error for β_outside; black line: value of the coefficient of variation of the posterior distributions obtained when we using the default values of fixed parameters; if the relative error value is within the two black lines, the effect of fixed parameters values on parameter estimates in the model is considered limited; qSICCT: percentage of SITT-negative animals tested 6 weeks after by SICCT; see table 2 for the definition of the other parameters.
